Hi,
I just installed a new system with 5.2.1 which shall serve as a NFS
server. While testing the performance of the system was VERY slow.
I could read from the server with about 500KB/s and write to it with
3,5MB/s on a 100MBit link.
copying from the server:
vr0 in 9.138 KB/s 26.394 KB/s 304.019 MB
out 505.639 KB/s 505.639 KB/s 1.236 GB
copying to the server:
vr0 in 3.219 MB/s 3.219 MB/s 377.028 MB
out 79.540 KB/s 79.540 KB/s 1.248 GB
I then upgraded to 5.3-BETA4 which gives me the same results.
Is there anything I'm missing here? The system is Athlon UP system with
a via-rhine network card. I tried to set various sysctls e.g.
vm.old_msync=1 and debug.mpsafenet=0 which did not help.
One strange thing was that after some reboots I got once a rate of 9MB/s
but after the next reboot this was gone :)
Using FTP for data transport the rate is around 10Mb/s which is quite
normal so this seems to be no NIC issue.
